Recombinant Human IGF1R Protein, His-tagged, Alexa Fluor 647 conjugated

Specification :
| Source : HEK293 | Species : Human | Tag : His | Form : Lyophilized | Molecular Mass : The calculated molecular masses for α subunit, β subunit and the single chain of the receptor are approximately 81 kDa, 23 kDa and 104 kDa, respectively. As a result of glycosylation, the recombinant single chain, α subunit and β subunit have apparent molecular masses of approximately 150 kDa, 120 kDa and 48 kDa, respectively in SDS-PAGE under reducing conditions. | Endotoxin : | Characteristic : Disulfide-linked homodimerLabeled with Alexa Fluor 647 via aminesExcitation = 650 nmEmission = 668 nm | Stability : Samples are stable for up to 12 months from date of receipt at -70 centigrade. | Storage : Store it under sterile conditions at -20 to -70 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | Storage Buffer : Lyophilized from sterile PBS Buffer, pH 7.4 | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
